Our Background

      Oil States International, Inc. was originally incorporated in July 1995 as CE Holdings, Inc. On August 1, 1995, CE Holdings, Inc. acquired Continental Emsco Company, an operator of oilfield supply stores, including its then wholly owned subsidiary Oil States Industries, Inc. (Oil States Industries). Oil States Industries is a manufacturer of offshore products.

      In May 1996, Oil States Industries purchased the construction division of Hunting Oilfield Services, Ltd., which provides a variety of construction products and services to the offshore oil and gas industry as well as certain connector manufacturing technology. In November 1996, CE Holdings, Inc. changed its name to CONEMSCO, Inc. (Conemsco).

      In July 1997, Conemsco purchased HydroTech Systems, Inc., a full service provider of engineered products to the offshore pipeline industry, and SMATCO Industries Inc., a manufacturer of marine winches for the offshore service boat industry. In December 1997, Conemsco purchased Gregory Rig Service & Sales Inc., a provider of drilling equipment and services.

      In February 1998, Conemsco acquired Subsea Ventures, Inc. (SVI). SVI designs, manufactures and services auxiliary structures for subsea blowout preventors and subsea production systems. In April 1998, Conemsco acquired the assets of Klaper (UK) Limited, a provider of repair and maintenance services for blowout preventors and drilling risers used in offshore drilling.

      In July 2000, Conemsco changed its name to Oil States International, Inc. In July 2000, Oil States International, Inc., HWC Energy Services, Inc. (HWC), PTI Group Inc. (PTI) and Sooner Inc. (Sooner) entered into a Combination Agreement (the Combination Agreement) providing that, concurrently with the closing of our initial public offering, HWC, PTI and Sooner would merge with wholly owned subsidiaries of Oil States (the Combination). As a result, HWC, PTI and Sooner became wholly owned subsidiaries of Oil States in February 2001. In this Annual Report on Form 10-K, references to the “Company” or to “we,” “us,” “our,” and similar terms are to Oil States International, Inc. and its subsidiaries following the Combination and references to “Oil States” are to Oil States International, Inc. and its subsidiaries prior to the Combination.

Acquisitions

      Since the completion of our initial public offering in February 2001, we have completed 30 acquisitions for total consideration of $340 million. Acquisitions of other oil service businesses have been an important aspect of our growth strategy and plans to increase shareholder value.

      In 2002, we acquired the following six businesses for total consideration of approximately $72.1 million, which was financed primarily with borrowings under our credit facility:

      In 2003, we spent $16.8 million, financed with borrowings under our credit facility, to acquire five businesses. Three of the businesses were rental tool companies acquired for a total consideration of $10.5 million. The acquired rental tool companies conduct operations in South Texas and Louisiana and were combined with our existing rental tool business within our well site services segment. The remaining two businesses, acquired for aggregate consideration of $6.3 million, were combined with our offshore products segment.

      In 2004, we acquired six rental tool businesses, a tubular distribution business and a small tooling line for total consideration of $89.1 million. In January 2004, we acquired the stock of five related rental tool companies for $36.6 million and in April 2004 we acquired the assets of a rental tool business for $4.8 million. In May 2004, we purchased the oil country tubular goods (“OCTG”) distribution business of Hunting Energy Services, L.P for $47.2 million. In October 2004, we acquired a tooling product line into our offshore products segment for $0.5 million.

      In 2005, we completed the acquisitions of a land drilling business, a rental tool company, a tubular distributor, a remote accommodation fabrication business and a small offshore products line for total consideration of $158.5 million.

      On February 1, 2005, we completed the acquisition of Elenburg Exploration Company, Inc. (Elenburg), a Wyoming based land drilling company for total consideration of $22.1 million, including transaction costs and a note payable to the former owners of $0.8 million. At the date of acquisition, Elenburg owned and operated seven rigs which provided shallow land drilling services in Montana, Wyoming, Colorado, and Utah. The Elenburg acquisition allowed us to expand its land drilling business into different geographic areas.

      Effective May 1, 2005 and June 1, 2005, we acquired Stinger Wellhead Protection, Inc., certain affiliated companies and related intellectual property, (collectively, Stinger) for total consideration of $96.1 million, including transaction costs and a note payable to the former owners of $5.0 million. Stinger provides wellhead isolation equipment and services through its 29 locations in the United States, Canada, Central and South America. Stinger’s patented equipment is utilized during pressure pumping operations and isolates the customers’ blow-out preventers or wellheads from the pressure and abrasion experienced during the fracturing process of an oil or gas well. The Stinger acquisition expanded our rental tool and services capabilities, especially in the pressure pumping market.

      On June 2, 2005, we purchased Phillips Casing and Tubing, L.P. (Phillips) for total consideration of $31.2 million including transaction costs. Phillips distributes oil country tubular goods (OCTG), primarily carbon ERW (electronic resistance welded) pipe, from its facilities in Midland and Godley, Texas. Phillips distribution operations were merged into our existing distribution operations in our tubular services segment.

      On June 6, 2005, we acquired Noble Structures, Inc. (Noble) for total consideration of $8.7 million, including transaction costs and a note payable of $0.8 million. The acquisition expanded the Company’s accommodation manufacturing capabilities in Canada in order to meet increased demand for remote site facilities, principally in the oil sands region.

      In December 2005, we acquired a product line into our offshore products segment for cash consideration of $0.4 million.

      The cash consideration paid for all of the Company’s acquisitions during 2005 was initially funded utilizing its existing bank credit facility and a $25 million bridge loan (See Note 7 to the Consolidated Financial Statements included in this Annual Report on Form 10-K).

Workover Business Merger

      On November 12, 2005, we announced that one of our subsidiaries signed a definitive agreement to combine its hydraulic workover business with Boots & Coots International Well Control, Inc. (Amex: WEL) (“Boots & Coots”) in exchange for 26.5 million shares of Boots & Coots common stock and senior subordinated promissory notes totaling $15.0 million. The transaction is subject to the approval of Boots & Coots’ shareholders and is expected to close in March 2006.

      As discussed herein, our hydraulic workover business is based in Houma, Louisiana, provides live and dead well workover services throughout the world, utilizing a fleet of 27 owned and operated hydraulic workover units. Our workover operations are performed in the U.S., Venezuela, Algeria, West Africa and the Middle East. Financial information for our workover operations is included in Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations and in our Consolidated Financial Statements at Footnote No. 13 — Segment and Related Information under the caption “Hydraulic Workover”.

      Upon the closing of the transaction, Oil States will own approximately 44% of the combined company and will receive senior subordinated promissory notes totaling $15.0 million in aggregate principal from Boots & Coots bearing a fixed annual interest rate of 10% and maturing four and one half years from the closing of the transaction. The senior subordinated notes are subject to increase at closing depending upon the level of working capital at closing. In addition, we have the right under the transaction agreement to nominate three additional members to Boots & Coots’ existing five-member Board of Directors.

Our Industry

      We operate in the oilfield service industry and provide products and services to oil and gas exploration and production companies for use in the drilling for and production of oil and gas. Demand for our products and services is cyclical and substantially dependent upon activity levels in the oil and gas industry, particularly our customers’ willingness to spend capital on the exploration and development of oil and gas reserves. Demand for our products and services by our customers is highly sensitive to current and expected oil and natural gas prices. See Note 13 to our Consolidated Financial Statements included in this Annual Report on Form 10-K for financial information by segment and a geographical breakout of revenues and long-lived assets.

      Our financial results reflect the cyclical nature of the oilfield services business. Since 2001, there have been periods of increasing and decreasing activity in each of our operating segments.

      Our Well Site Services businesses, which is significantly affected by the North American rig count, had increased activity during 2001, saw decreased activity in 2002 and early 2003 and has seen increasing activity from 2003 through the current period. Acquisitions and capital expenditures made in this segment have

created additional growth opportunities. In addition, the increased activity supporting oil sands developments in northern Alberta, Canada by our work force accommodations, catering and logistics business in this segment have had an important positive impact on this segment’s overall trends.

      Our Offshore Products segment, which is more influenced by deepwater development activity and rig construction and repair, experienced increased activity during 2002 and 2003 as we shipped projects from our backlog which had increased in 2001 and 2002. In 2004, activity in this segment slowed; however, backlog increased during 2004 and 2005, which resulted in improved operating results during 2005.

      Our Tubular Services business is influenced by some of the same factors as our Well Site Services. In addition, during 2004 and 2005, this segment was significantly affected by increasing prices for steel products, including the oil country tubular goods (“OCTG”) we sell.

Well Site Services

      During the year ended December 31, 2005, we generated approximately 36% of our revenue and 51% of our operating income, before corporate charges, from our well site services segment. Our well site services segment provides a broad range of products and services that are used to establish and maintain the flow of oil and gas from a well throughout its lifecycle. Our services include workover services, drilling services, rental equipment, work force accommodations, catering and logistics services and modular building construction services. We use our fleet of workover and drilling rigs, rental equipment, work force accommodation facilities and related equipment to service well sites for oil and natural gas companies. Our products and services are used in both onshore and offshore applications through the exploration, development, production and abandonment phases of a well’s life. Additionally, our work force accommodations, catering and logistics services are employed in a variety of mining and related natural resource applications as well as forest fire fighting.

      Demand for our workover and drilling rigs, rental equipment and work force accommodations, catering and logistics services has historically been tied to the level of activity by oil and gas explorationists and producers. The primary driver for this activity is the price of oil and natural gas. Activity levels have been and we expect will continue to be highly correlated with product prices.

      Workover Services. We provide our workover products and services primarily to customers in the U.S., Venezuela, the Middle East, North and West Africa, for both onshore and offshore applications. Workover products and services are used in operations on a producing well to restore or increase production. Workover services are typically used during the development, production and abandonment stages of the well. Our hydraulic workover units are used for workover operations and snubbing operations in pressure situations.

      A hydraulic workover unit is a specially designed rig used for moving tubulars in and out of a wellbore using hydraulic pressure. These units may be used for servicing wells that are not producing or for working on wells under pressure. These units may be used for underbalanced drilling and workover and also in well control applications. When a unit is snubbing, it is pushing pipe or tubulars into the well bore against well bore pressures. Because of their small size and ability to work on wells under pressure, hydraulic workover units offer some advantages over larger workover rigs and conventional drilling rigs. However, most wells where we perform workover service are wells with no pressure.

      As of December 31, 2005, we had 27 “stand alone” hydraulic workover units. Of these 27 units, 14 were located in the U.S., five were located in Venezuela, four were located in Dubai, U.A.E., two were located in Egypt and two were located in the Republic of Congo. In addition, we had labor and maintenance contracts on two non-owned hydraulic workover units in Algeria. Typically, our hydraulic workover units are contracted on a short-term dayrate basis. As a result, utilization of our hydraulic workover units varies from period to period.

Our utilization rate for hydraulic workover units was 32.9% in 2005 and 29.1% during 2004. As of December 31, 2005, eleven of our hydraulic workover units were working or under contract and we had crews on two managed units in Algeria. The length of time necessary to complete a job depends on many factors, including the number of wells and the type of workover or pressure control situation involved. Usage of our hydraulic workover units is also affected by the availability of trained personnel. With our current level of trained personnel, we estimate that we have the capability to crew and operate 12 to 14 simultaneous jobs involving our hydraulic workover units.

      Drilling Services. Our drilling services business is located in Odessa, Texas, Wooster, Ohio and Casper, Wyoming and provides drilling services for shallow to medium depths ranging from 2,000 to 11,500 feet. Drilling services are typically used during the exploration and development stages of a field. We have a total of 27 semi-automatic drilling rigs with hydraulic pipe handling booms and lift capacities ranging from 200,000 to 300,000 pounds. We added one of these drilling rigs in 2003, one in each of February and December 2004, seven in February 2005 (through our acquisition of Elenburg) and one in each of June and August 2005. Fifteen of these drilling rigs are located in Odessa, Texas, eight in the Rocky Mountain region and four are located in Wooster, Ohio. As of December 31, 2005, all 27 rigs were working or under contract. Utilization decreased slightly from 90.5% in 2004 to 87.8% in 2005. We have assembled five of our new rigs that have been added to our fleet during 2003 through 2005 in our Odessa, Texas facility with components purchased from specialty vendors. Two additional rigs were under construction in Odessa, Texas at December 31, 2005, one of which spudded its first well in February 2006 and one which should commence operations by October 2006. We may continue to add rigs depending upon our market outlook.

      We market our drilling services directly to a diverse customer base, consisting of both major and independent oil companies. During 2005 we switched from billing on a footage basis to billing on a dayrate basis for many of our drilling rigs. Under a daywork drilling contract, the customer pays for certain costs that the Company would normally provide when drilling on a footage basis and assumes more risk than on a footage basis. The land drilling business is highly fragmented and consists of a small number of large companies and many smaller companies.

      Rental Equipment. Our rental equipment business provides a wide range of products for use in the offshore and onshore oil and gas industry, including:

      Our rental equipment is used during the exploration, development, production and abandonment stages. As of December 31, 2005, we provided rental equipment at 52 U.S. distribution points in Texas, Louisiana, Oklahoma, Mississippi, New Mexico, Wyoming, California, Colorado, North Dakota, Utah, Canada, Mexico and Argentina. We provide rental equipment on a day rental basis with rates varying depending on the type of equipment and the length of time rented. In certain operations, we also provide service personnel in connection with the equipment rental.

      Work Force Accommodations, Catering and Logistics and Modular Building Construction. We are a large provider of integrated products and services to support workers in remote locations, including work force accommodation, food services, remote site management services and modular building construction. We provide complete design, manufacture, installation, operation and redeployment logistics services for oil and gas drilling, oil sands development in the Fort McMurray region of Northern Canada, diamond mining in Northern Canada and other mining ventures throughout the world, pipeline construction, forestry, offshore construction, disaster relief services and support services for military operations on a worldwide basis. Our work force products and service operations are primarily focused in Canada and the Gulf of Mexico although we also have performed catering and facilities management activities in other international areas. During the

peak of our operating season, we typically provide these services in over 200 separate locations with separate location populations ranging from 20 to 2,000 persons. We design, construct and install a variety of portable modular buildings, including housing, kitchens, recreational units and offices for lease or sale to the Canadian and Gulf of Mexico markets. Our designers work closely with our clients to build structures that best serve their needs.

Offshore Products

      During the year ended December 31, 2005, we generated approximately 18% of our revenue and 13% of our operating income, before corporate charges, from our offshore products segment. Through this segment, we design and manufacture a number of cost-effective, technologically advanced products for the offshore energy industry. In addition, we have other lower margin products and services such as fabrication and inspection services. Our products and services are used in both shallow and deepwater producing regions and include flex-element technology, advanced connector systems, blow-out preventor stack integration and repair services, deepwater mooring and lifting systems, offshore equipment and installation services and subsea pipeline products. We have facilities in Arlington, Houston and Lampasas, Texas; Houma, Louisiana; Tulsa, Oklahoma; Scotland; Brazil; England; Singapore and Thailand that support our offshore products segment.

      The market for our offshore products and services depends primarily upon development of infrastructure for offshore production activities, drilling rig refurbishments and upgrades and new rig construction. As demand for oil and gas increases and related drilling and production increases in offshore areas throughout the world, particularly in deeper water, we expect spending on these activities to increase.

      The upgrade of existing rigs to equip them with the capability to drill in deeper water and withstand harsh operating conditions, the construction of new deepwater-capable rigs, and the installation of fixed or floating production systems require specialized products and services like the ones we provide.

      Our offshore products segment provides a broad range of products and services for use in offshore drilling and development activities. In addition, this segment provides onshore oil and gas, defense and general industrial products and services. Our offshore products segment is dependent on the industry’s continuing innovation and creative applications of existing technologies.

      We design and build manufacturing and testing systems for many of our new products and services. These testing and manufacturing facilities enable us to provide reliable, technologically advanced products and services. Our Aberdeen facility provides structural testing including full-scale product simulations.

      Offshore Development and Drilling Activities. We design, manufacture, fabricate, inspect, assemble, repair, test and market subsea equipment and offshore vessel and rig equipment. Our products are components of equipment used for the drilling and production of oil and gas wells on offshore fixed platforms and mobile production units, including floating platforms and floating production, storage and offloading vessels, and on other marine vessels, floating rigs and jack-ups. Our products and services include:

      Flexible Bearings and Connector Products. We are the principal supplier of flexible bearings, or FlexJoints^®, to the offshore oil and gas industry. We also supply connections and fittings that join lengths of large diameter conductor or casing used in offshore drilling operations. FlexJoints^® are flexible bearings that permit movement of riser pipes or tension leg platform tethers under high tension and pressure. They are used on drilling, production and export risers and are used increasingly as offshore production moves to deeper water areas. Drilling riser systems provide the vertical conduit between the floating drilling vessel and the subsea wellhead. Through the drilling riser, equipment is guided into the well and drilling fluids are returned to the surface. Production riser systems provide the vertical conduit from the subsea wellhead to the floating production platform. Oil and gas flows to the surface for processing through the production riser. Export risers provide the vertical conduit from the floating production platform to the subsea export pipelines. FlexJoints^® are a critical element in the construction and operation of production and export risers on floating production systems in deepwater.

      Floating production systems, including Tension Leg Platforms, Spars and FPSO facilities, are a significant means of producing oil and gas, particularly in deepwater environments. We provide many important products for the construction of these facilities. A tension leg platform is a floating platform that is moored by vertical pipes, or tethers, attached to both the platform and the sea floor. Our FlexJoint^® tether bearings are used at the top and bottom connections of each of the tethers, and our Merlin connectors are used to join shorter pipe sections to form long pipes offshore. A Spar is a floating vertical cylindrical structure which is approximately six to seven times longer than its diameter and is anchored in place. Our FlexJoints^® are also used to attach the steel catenary risers to a Spar or FPSO and for use on import or export risers.

      Subsea Pipeline Products. We design and manufacture a variety of fittings and connectors used in offshore oil and gas pipelines. Our products are used for new construction, maintenance and repair applications. New construction fittings include:

      We provide diverless connection systems for subsea flowlines and pipelines. Our HydroTech^® collet connectors provide a high-integrity, proprietary metal-to-metal sealing system for the final hook-up of deep offshore pipelines and production systems. They also are used in diverless pipeline repair systems and in future pipeline tie-in systems. Our lateral tie-in sled, which is installed with the original pipeline, allows a subsea tie-in to be made quickly and efficiently using proven HydroTech^® connectors without costly offshore equipment mobilization and without shutting off product flow.

      We provide pipeline repair hardware, including deepwater applications beyond the depth of diver intervention. Our products include:

      Marine Winches, Mooring and Lifting Systems and Rig Equipment. We design, engineer and manufacture marine winches, mooring and lifting systems and rig equipment. Our Skagit^® winches are specifically designed for mooring floating and semi-submersible drilling rigs and positioning pipelay and derrick barges, anchor handling boats and jack-ups, while our Nautilus^® marine cranes are used on production platforms throughout the world. We also design and fabricate rig equipment such as automatic pipe racking and blow-

out preventor handling equipment. Our engineering teams, manufacturing capability and service technicians who install and service our products provide our customers with a broad range of equipment and services to support their operations. Aftermarket service and support of our installed base of equipment to our customers is also an important source of revenues to us.

      BOP Stack Assembly, Integration, Testing and Repair Services. We design and fabricate lifting and protection frames and offer system integration of blow-out preventor stacks and subsea production trees. We can provide complete turnkey and design fabrication services. We also design and manufacture a variety of custom subsea equipment, such as riser flotation tank systems, guide bases, running tools and manifolds. In addition, we also offer blow-out preventor and drilling riser testing and repair services.

      Other Products and Services. We provide equipment for securing subsea structures and offshore platform jackets, including our Hydra-Lok^® hydraulic system. The Hydra-Lok^® tool, which has been successfully used at depths of 3,000 feet, does not require diver intervention or guide lines.

      We also provide cost-effective, standardized leveling systems for offshore structures that are anchored by foundation piles, including subsea templates, subsea manifolds and platform jackets.

      Our offshore products segment also produces a variety of products for use in applications other than in the offshore oil and gas industry. For example, we provide:

      Backlog. Backlog in our offshore products segment was $110.7 million at December 31, 2005, compared to $97.5 million at December 31, 2004 and $62.6 million at December 31, 2003. We expect the majority of our backlog at December 31, 2005 to be completed in 2006. Our offshore products backlog consists of firm customer purchase orders for which satisfactory credit or financing arrangements exist and delivery is scheduled. In some instances, these purchase orders are cancelable by the customer, subject to the payment of termination fees and/or the reimbursement of our costs incurred. Although our backlog is an important indicator of future offshore products shipments and revenues, backlog as of any particular date may not be indicative of our actual operating results for any future period. We believe that the offshore construction and development business is characterized by lengthy projects and a long “lead-time” order cycle. The change in backlog levels from one period to the next does not necessarily evidence a long-term trend.

      Our offshore products segment provides products and services to customers in the major offshore oil and gas producing regions of the world, including the Gulf of Mexico, West Africa, the North Sea, Brazil and Southeast Asia.

      We market our products and services to a broad customer base, including the direct end users, engineering and design companies, prime contractors, and at times, our competitors through outsourcing arrangements.

Tubular Services

      During the year ended December 31, 2005, we generated approximately 46% of our revenue and 36% of our operating income, before corporate charges, from our tubular services segment. Through this segment, we distribute oil country tubular goods, or OCTG, and provide associated OCTG finishing and logistics services

to the oil and gas industry. Oil country tubular goods consist of downhole casing and production tubing. Through our tubular services segment, we:

      We serve a customer base ranging from major oil companies to small independents. Through our key relationships with more than 20 domestic and foreign manufacturers and related service providers and suppliers of OCTG, we deliver tubular products and ancillary services to oil and gas companies, drilling contractors and consultants predominantly in the United States. The OCTG distribution market is highly fragmented and competitive, and is focused in the United States. We purchase tubular goods from a variety of sources. However, during 2005, we purchased from a single domestic supplier 52% of the tubular goods we distributed and from three domestic suppliers approximately 73% of such tubular goods.

      Our tubular services segment primarily distributes casing and tubing. Casing forms the structural wall in oil and gas wells to provide support, control pressure and prevent caving during drilling operations. Casing is also used to protect water-bearing formations during the drilling of a well. Casing is generally not removed after it has been installed in a well. Production tubing, which is used to bring oil and gas to the surface, may be replaced during the life of a producing well.

      A key indicator of domestic demand for OCTG is the average number of drilling rigs operating in the United States. The OCTG market at any point in time is also affected by the level of inventories maintained by manufacturers, distributors and end users. Demand for tubular products is positively impacted by increased drilling of deeper, horizontal and offshore wells. Deeper wells require incremental tubular footage and enhanced mechanical capabilities to ensure the integrity of the well. Premium tubulars are used in horizontal drilling to withstand the increased bending and compression loading associated with a horizontal well. Operators typically specify premium tubulars for the completion of offshore wells.

      Tubular Products and Services. We distribute various types of OCTG produced by both domestic and foreign manufacturers to major and independent oil and gas exploration and production companies and other OCTG distributors. We do not manufacture any of the tubular goods that we distribute. As a result, gross margins in this segment are generally lower than those reported by our other segments. We operate our tubular services segment from a total of eight offices and facilities located near areas of oil and gas exploration and development activity. We have distribution relationships with most major domestic and certain international steel mills.

      In this business, inventory management is critical to our success. We maintain on-the-ground inventory in approximately 60 yards located in the United States, giving us the flexibility to fill our customers’ orders from our own stock or directly from the manufacturer. We have a proprietary inventory management system, designed specifically for the OCTG industry, that enables us to track our product shipments down to the individual joint of pipe.

      A-Z Terminal. Our A-Z Terminal pipe maintenance and storage facility in Crosby, Texas is equipped to provide a full range of tubular services, giving us strong customer service capabilities. Our A-Z Terminal is on 109 acres, is an ISO 9001-certified facility and has more than 1,400 pipe racks and two double-ended thread lines. We have exclusive use of a permanent third-party inspection center within the facility. The facility also includes indoor chrome storage capability and patented pipe cleaning machines.

      We offer services at our A-Z Terminal facility typically outsourced by other distributors, including the following: threading, inspection, cleaning, cutting, logistics, rig returns, installation of float equipment and non-destructive testing.

      Other Facilities. We also offer tubular services at our facilities in Midland, Texas and Godley, Texas which were added in the Phillips acquisition. Our Midland, Texas facility covers approximately 50 acres and has more than 400 pipe racks. Our Godley, Texas facility, which services the Barnett shale area, has approximately 60 pipe racks on approximately 13 developed acres and is serviced by a rail spur. Independent third party inspection companies operate within these facilities.

      Tubular Products and Services Sales Arrangements. We provide our tubular products and logistics services through a variety of arrangements, including spot market sales and alliances. We provide some of our tubular products and services to independent and major oil and gas companies under alliance arrangements. Although our alliances are generally not as profitable as the spot market and can be cancelled by the customer, they provide us with more stable and predictable revenues and an improved ability to forecast required inventory levels, which allows us to manage our inventory more efficiently.

      Our tubular services segment provides tubular products and services principally to customers in the United States both for land and offshore applications. However, we also sell a small percentage for export to other countries, including Brazil, Cameroon, Chad, Columbia, Congo, Ecuador, Egypt, Equatorial Guinea, Gabon, Germany, Guatemala, Hungary, Netherlands, Russian Federation, Scotland, Trinidad, Tunisia and Venezuela.

      Our three largest end-user customers in the tubular distribution market in 2005 were ChevronTexaco Corporation, Burlington Resources and ConocoPhillips. Our three largest suppliers were U.S. Steel Group, Lone Star Steel and Maverick Tube Corporation. Although we have a leading market share position in tubular services distribution, the market is highly fragmented. Our main competitors in tubular distribution are privately owned distributors including Total Premier, Red Man Pipe & Supply Co., Inc., Bourland and Leverich and Pipeco Services.

Employees

      As of December 31, 2005, we had approximately 5,236 full-time employees, 26% of whom are in our offshore products segment, 72% of whom are in our well site services segment and 2% of whom are in our tubular services segment. We are party to collective bargaining agreements covering 780 employees located in Canada and the United Kingdom as of December 31, 2005. We believe relations with our employees are good.

Government Regulation

      Our business is significantly affected by foreign, federal, state and local laws and regulations relating to the oil and natural gas industry, worker safety and environmental protection. Changes in these laws, including more stringent regulations and increased levels of enforcement of these laws and regulations, could significantly affect our business. We cannot predict changes in the level of enforcement of existing laws and regulations or how these laws and regulations may be interpreted or the effect changes in these laws and regulations may have on us or our future operations or earnings. We also are not able to predict whether additional laws and regulations will be adopted.

      We depend on the demand for our products and services from oil and natural gas companies. This demand is affected by changing taxes, price controls and other laws and regulations relating to the oil and gas industry generally, including those specifically directed to oilfield and offshore operations. The adoption of laws and regulations curtailing exploration and development drilling for oil and natural gas in our areas of operation could also adversely affect our operations by limiting demand for our products and services. We

cannot determine the extent to which our future operations and earnings may be affected by new legislation, new regulations or changes in existing regulations or enforcement.

      Some of our employees who perform services on offshore platforms and vessels are covered by the provisions of the Jones Act, the Death on the High Seas Act and general maritime law. These laws operate to make the liability limits established under states’ workers’ compensation laws inapplicable to these employees and permit them or their representatives generally to pursue actions against us for damages or job-related injuries with no limitations on our potential liability.

      Our operations are subject to numerous foreign, federal, state and local environmental laws and regulations governing the release and/or discharge of materials into the environment or otherwise relating to environmental protection. Numerous governmental agencies issue regulations to implement and enforce these laws, for which compliance is often costly and difficult. The violation of these laws and regulations may result in the denial or revocation of permits, issuance of corrective action orders, assessment of administrative and civil penalties, and even criminal prosecution. We believe that we are in substantial compliance with applicable environmental laws and regulations. Further, we do not anticipate that compliance with existing environmental laws and regulations will have a material effect on our consolidated financial statements. However, there can be no assurance that substantial costs for compliance will not be incurred in the future. Moreover, it is possible that other developments, such as the adoption of stricter environmental laws, regulations and enforcement policies, could result in additional costs or liabilities that we cannot currently quantify.

      We generate wastes, including hazardous wastes, that are subject to the federal Resource Conservation and Recovery Act, or RCRA, and comparable state statutes. The United States Environmental Protection Agency, or EPA, and state agencies have limited the approved methods of disposal for some types of hazardous and nonhazardous wastes. Some wastes handled by us in our field service activities that currently are exempt from treatment as hazardous wastes may in the future be designated as “hazardous wastes” under RCRA or other applicable statutes. This would subject us to more rigorous and costly operating and disposal requirements.

      The federal Comprehensive Environmental Response, Compensation, and Liability Act, CERCLA or the “Superfund” law, and comparable state statutes impose liability, without regard to fault or legality of the original conduct, on classes of persons that are considered to have contributed to the release of a hazardous substance into the environment. These persons include the owner or operator of the disposal site or the site where the release occurred and companies that disposed of or arranged for the disposal of the hazardous substances at the site where the release occurred. Under CERCLA, these persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment and for damages to natural resources, and it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment. We currently have operations on properties where activities involving the handling of hazardous substances or wastes may have been conducted prior to our operations on such properties or by third parties whose operations were not under our control. These properties may be subject to CERCLA, RCRA and analogous state laws. Under these laws and related regulations, we could be required to remove or remediate previously discarded hazardous substances and wastes or property contamination that was caused by these third parties. These laws and regulations may also expose us to liability for our acts that were in compliance with applicable laws at the time the acts were performed.

      In the course of our operations, some of our equipment may be exposed to naturally occurring radiation associated with oil and gas deposits, and this exposure may result in the generation of wastes containing naturally occurring radioactive materials or “NORM.” NORM wastes exhibiting trace levels of naturally occurring radiation in excess of established state standards are subject to special handling and disposal requirements, and any storage vessels, piping, and work area affected by NORM may be subject to remediation or restoration requirements. Because many of the properties presently or previously owned, operated, or occupied by us have been used for oil and gas production operations for many years, it is possible that we may incur costs or liabilities associated with elevated levels of NORM.

      The Federal Water Pollution Control Act and analogous state laws impose restrictions and strict controls regarding the discharge of pollutants into state waters or waters of the United States. The discharge of pollutants into jurisdictional waters is prohibited unless the discharge is permitted by the EPA or applicable state agencies. Many of our properties and operations require permits for discharges of wastewater and/or stormwater, and we have a system for securing and maintaining these permits. In addition, the Oil Pollution Act of 1990 imposes a variety of requirements on responsible parties related to the prevention of oil spills and liability for damages, including natural resource damages, resulting from such spills in waters of the United States. A responsible party includes the owner or operator of a facility or vessel, or the lessee or permittee of the area in which an offshore facility is located. The Federal Water Pollution Control Act and analogous state laws provide for administrative, civil and criminal penalties for unauthorized discharges and, together with the Oil Pollution Act, impose rigorous requirements for spill prevention and response planning, as well as substantial potential liability for the costs of removal, remediation, and damages in connection with any unauthorized discharges.

      Some of our operations also result in emissions of regulated air pollutants. The federal Clean Air Act and analogous state laws require permits for facilities that have the potential to emit substances into the atmosphere that could adversely affect environmental quality. Failure to obtain a permit or to comply with permit requirements could result in the imposition of substantial administrative, civil and even criminal penalties.

Risks Related to Our Business Generally

      We depend upon the oil and gas industry and its ability and willingness to make expenditures which are directly affected by trends in oil and natural gas prices. Demand for our products and services is particularly sensitive to the level of exploration, development and production activity of, and the corresponding capital spending by, oil and natural gas companies, including national oil companies. If our customers’ expenditures decline, our business will suffer. The industry’s willingness to explore, develop and produce depends largely upon the availability of attractive drilling prospects and the prevailing view of future product prices. Prices for oil and natural gas are subject to large fluctuations in response to relatively minor changes in the supply of and demand for oil and natural gas, market uncertainty, and a variety of other factors that are beyond our control. Product prices have been at historically high levels over recent months, which has helped to substantially increase our financial results. A sudden or long term decline in product pricing could materially adversely affect our results of operations. Any prolonged reduction in oil and natural gas prices will depress levels of exploration, development, and production activity, often reflected as reductions in rig counts. Such lower activity levels could materially adversely affect our revenue and profitability. Many factors affect the supply and demand for oil and gas and therefore influence product prices, including:

      Our offshore products segment depends on exploration and production expenditures in deepwater areas. Because deepwater projects are more capital intensive and take longer to generate first production than shallow water and onshore projects, the economic analyses conducted by exploration and production companies typically assume lower prices for production from such projects to determine economic viability over the long term. Perceptions of longer-term lower oil and natural gas prices by oil and gas companies can reduce or defer major expenditures given the long-term nature of many large scale development projects, which would adversely affect our revenues and profitability.

      Oil prices have been and are expected to remain volatile. This volatility causes oil and gas companies and drilling contractors to change their strategies and expenditure levels. We have experienced in the past, and we may experience in the future, significant fluctuations in operating results based on these changes.

      We have operations in various international areas, including parts of Africa, South America and the Middle East. Our operations in these areas increase our exposure to risks of war, terrorist attacks, local economic conditions, political disruption, civil disturbance and governmental policies that may:

      Our international business operations include projects in countries where our competitors who are not subject to United States laws and regulations, such as the Foreign Corrupt Practices Act, can gain competitive advantages over us by securing business awards, licenses or other preferential treatment in those jurisdictions using methods that United States law and regulations prohibit us from using. For example, our non-U.S. competitors are not subject to the anti-bribery restrictions of the Foreign Corrupt Practices Act, which make it illegal to give anything of value to foreign officials or employees or agents of nationally owned oil companies in order to obtain or retain any business or other advantage. We may be subject to competitive

disadvantages to the extent that our competitors are able to secure business, licenses or other preferential treatment by making payments to government officials and others in positions of influence.

      Many of the products that we sell, especially in our offshore products segment, are complex and highly engineered and often must perform in harsh conditions. We believe that our success depends upon our ability to employ and retain technical personnel with the ability to design, utilize and enhance these products. In addition, our ability to expand our operations depends in part on our ability to increase our skilled labor force. The demand for skilled workers is high, and the supply is limited. We have already experienced high demand and increased wages for labor forces serving our well site services segment, notably in our accommodations business in Canada. Significant increases in the wages paid by competing employers could further result in a reduction of our skilled labor force, increases in the wage rates that we must pay or both. When these events occur, our cost structure increases and our growth potential could be impaired.

      U.S. law currently restricts imports of low-cost tubular goods from a number of foreign countries into the U.S. tubular goods market, resulting in higher prices for tubular goods. If these restrictions were to be lifted or if the level of imported low-cost tubular goods were to otherwise increase, our tubular services segment could be adversely affected to the extent that we then have higher-cost tubular goods in inventory. If prices were to decrease significantly, we might not be able to profitably sell our inventory of tubular goods. In addition, significant price decreases could result in a longer holding period for some of our inventory, which could also have a material adverse effect on our tubular services segment.

      We do not manufacture any of the tubular goods that we distribute. Historically, users of tubular goods in the United States, in contrast to outside the United States, have purchased tubular goods through distributors. If customers were to purchase tubular goods directly from steel mills, our results of operations could be adversely impacted.

      Our hydraulic well control and drilling operations and our offshore products business are significantly affected by stringent and complex foreign, federal, state and local laws and regulations governing the discharge of substances into the environment or otherwise relating to environmental protection. We could be exposed to liability for cleanup costs, natural resource damages and other damages as a result of our conduct that was lawful at the time it occurred or the conduct of, or conditions caused by, prior operators or other third parties. Environmental laws and regulations have changed in the past, and they are likely to change in the future. If existing regulatory requirements or enforcement policies change, we may be required to make significant unanticipated capital and operating expenditures.

      Any failure by us to comply with applicable environmental laws and regulations may result in governmental authorities taking actions against our business that could adversely impact our operations and financial condition, including the:

      Our operations are subject to many hazards. We face the following risks under our insurance coverage:

Even a partially uninsured claim, if successful and of significant size, could have a material adverse effect on our results of operations or consolidated financial position.

      In the ordinary course of business, we become the subject of various claims, lawsuits and administrative proceedings seeking damages or other remedies concerning our commercial operations, products, employees and other matters, including occasional claims by individuals alleging exposure to hazardous materials as a result of our products or operations. Some of these claims relate to the activities of businesses that we have sold, and some relate to the activities of businesses that we have acquired, even though these activities may have occurred prior to our acquisition of such businesses. We maintain insurance to cover many of our potential losses, and we are subject to various self-retentions and deductibles under our insurance. It is possible, however, that a judgment could be rendered against us in cases in which we could be uninsured and beyond the amounts that we currently have reserved or anticipate incurring for such matters.

      We sell our products and services in competitive markets. In some of our business segments, we compete with the oil and gas industry’s largest oilfield services providers. These companies have greater financial resources than we do. In addition, our business, particularly our tubular services business, may face competition from business-to-business internet auction activities. Our business will be adversely affected to the extent that these providers are successful in reducing purchases of our products and services.

Risks Related to Our Operations

      Our operations are directly affected by seasonal differences in weather in the areas in which we operate, most notably in Canada and the Gulf of Mexico. Our Canadian work force accommodations, catering and logistics operations are significantly focused on the winter months when the winter freeze in remote regions permits exploration and production activity to occur. The spring thaw in these frontier regions restricts operations in the spring months and, as a result, adversely affects our operations and sales of products and services in the second and third quarters. Our operations in the Gulf of Mexico are also affected by weather patterns. Weather conditions in the Gulf Coast region generally result in higher drilling activity in the spring, summer and fall months with the lowest activity in the winter months. In addition, summer and fall drilling activity can be restricted due to hurricanes and other storms prevalent in the Gulf of Mexico and along the Gulf Coast. During 2005, significant disruption occurred in oil and gas drilling and production operations in the U.S. Gulf of Mexico due to damage inflicted by hurricanes Katrina and Rita. As a result, full year results are not likely to be a direct multiple of any particular quarter or combination of quarters.

      We rely on a variety of intellectual property rights that we use in our offshore products and well site services segments, particularly our patents relating to our FlexJoint^® technology and intervention tools utilized

in the completion or workover of oil and gas wells. We may not be able to successfully preserve these intellectual property rights in the future and these rights could be invalidated, circumvented or challenged. In addition, the laws of some foreign countries in which our products and services may be sold do not protect intellectual property rights to the same extent as the laws of the United States. The failure of our company to protect our proprietary information and any successful intellectual property challenges or infringement proceedings against us could adversely affect our competitive position.

      The market for our offshore products is characterized by continual technological developments to provide better performance in increasingly greater depths and harsher conditions. If we are not able to design, develop and produce commercially competitive products in a timely manner in response to changes in technology, our business and revenues will be adversely affected.

      We depend on the continued employment and performance of key members of management. If any of our key managers resign or become unable to continue in their present roles and are not adequately replaced, our business operations could be materially adversely affected. We do not maintain “key man” life insurance for any of our officers.

      As of December 31, 2005, goodwill represented approximately 25% of our total assets. We have recorded goodwill because we paid more for some of our businesses than the fair market value of the tangible and separately measurable intangible net assets of those businesses. Current accounting standards, which were effective January 1, 2002, require a periodic review of goodwill for impairment in value and a non-cash charge against earnings with a corresponding decrease in stockholders’ equity if circumstances indicate that the carrying amount will not be recoverable. See Note 6 to our Consolidated Financial Statements included in this Annual Report on Form 10-K.

      During 2005, we purchased from a single domestic supplier approximately 52% of the tubular goods we distributed and from three domestic suppliers approximately 73% of such tubular goods. We do not have contracts with any of these suppliers. If we were to lose any of these suppliers or if production at one or more of the suppliers were interrupted, our tubular services segment and our overall business, financial condition and results of operations could be adversely affected. If the extent of the loss or interruption were sufficiently large, the impact on us would be material.

      Provisions contained in our certificate of incorporation and bylaws, such as a classified board, limitations on the removal of directors, on stockholder proposals at meetings of stockholders and on stockholder action by written consent and the inability of stockholders to call special meetings, could make it more difficult for a third party to acquire control of our company. Our certificate of incorporation also authorizes our board of directors to issue preferred stock without stockholder approval. If our board of directors elects to issue preferred stock, it could increase the difficulty for a third party to acquire us, which may reduce or eliminate our stockholders’ ability to sell their shares of common stock at a premium.

      Two of our directors, L.E. Simmons and Andrew L. Waite, are also current directors or officers of L.E. Simmons & Associates, Incorporated, the ultimate general partner of SCF-III, L.P. and SCF-IV, L.P., private equity funds that focus on investments in the energy industry (collectively, “SCF”). SCF owned 6.7% of our outstanding common stock as of December 31, 2005. This may create conflicts of interest because these directors have responsibilities to SCF and its owners. Their duties as directors or officers of L.E. Simmons & Associates, Incorporated may conflict with their duties as directors of our company regarding business dealings between SCF and us and other matters. The resolution of these conflicts may not always be in our or our stockholders’ best interest.

      Not applicable.

      The following table presents information about our principal properties and facilities. Except as indicated below, we own all of these properties or facilities.

      We have six tubular sales offices and a total of 52 rental tool supply and distribution points in Texas, Louisiana, New Mexico, Mississippi, Oklahoma, Wyoming, California, Colorado, North Dakota, Utah, Canada, Mexico and Argentina. Most of these office locations provide sales, technical support and personnel services to our customers. We also have various offices supporting our business segments which are both owned and leased.

      We are a party to various pending or threatened claims, lawsuits and administrative proceedings seeking damages or other remedies concerning our commercial operations, products, employees and other matters, including warranty and product liability claims and occasional claims by individuals alleging exposure to

hazardous materials as a result of our products or operations. Some of these claims relate to matters occurring prior to our acquisition of businesses, and some relate to businesses we have sold. In certain cases, we are entitled to indemnification from the sellers of businesses and in other cases, we have indemnified the buyers of businesses from us. Although we can give no assurance about the outcome of pending legal and administrative proceedings and the effect such outcomes may have on us, we believe that any ultimate liability resulting from the outcome of such proceedings, to the extent not otherwise provided for or covered by insurance, will not have a material adverse effect on our consolidated financial position, results of operations or liquidity.

      On February 18, 2005, we announced that we had conducted an internal investigation prompted by the discovery of over billings totaling approximately $400,000 by one of our subsidiaries (the “Subsidiary”) to a government owned oil company in South America. The over billings were detected by the Company during routine financial review procedures, and appropriate financial statement adjustments were included in its previously reported fourth quarter 2004 results. We and independent counsel retained by our audit committee conducted separate investigations consisting of interviews and a thorough examination of the facts and circumstances in this matter. We voluntarily reported the results of our investigation to the Securities and Exchange Commission (the “SEC”) and have fully cooperated with requests for information received from the SEC. The SEC recently completed its informal investigation of this matter. On October 31, 2005, our counsel received a “Wells Notice” from the staff of the SEC indicating that the staff has made a preliminary decision to recommend that the SEC bring a civil action against the Company alleging violations of provisions of the Securities and Exchange Act of 1934 relating to the maintenance of books, records and internal accounting controls and procedures as set forth in Sections 13(b)(2)(A) and (B) of the Act. The alleged violations related to this over billings matter. A “Wells Notice” is not a formal allegation or proof of wrongdoing. The Company has responded to the SEC staff regarding the “Wells Notice” and is in discussions with the SEC staff regarding this matter.

      No matters were submitted to a vote of security holders during the fourth quarter of 2005.

PART II

Common Stock Information

      Our authorized common stock consists of 200,000,000 shares of common stock. There were 49,192,972 shares of common stock outstanding as of February 10, 2006, including 267,348 shares of common stock issuable upon exercise of exchangeable shares of one of our Canadian subsidiaries. These exchangeable shares, which were issued to certain former shareholders of PTI in the Combination, are intended to have characteristics essentially equivalent to our common stock prior to the exchange. For purposes of this Annual Report on Form 10-K, we have treated the shares of common stock issuable upon exchange of the exchangeable shares as outstanding. The approximate number of record holders of our common stock as of February 10, 2006 was 62. Our common stock is traded on the New York Stock Exchange under the ticker symbol OIS. The closing price of our common stock on February 10, 2006 was $38.23 per share.

      The following table sets forth the range of high and low sale prices of our common stock.

      We have not declared or paid any cash dividends on our common stock since our initial public offering and do not intend to declare or pay any cash dividends on our common stock in the foreseeable future. Furthermore, our existing credit facilities restrict the payment of dividends. Any future determination as to the declaration and payment of dividends will be at the discretion of our Board of Directors and will depend on then existing conditions, including our financial condition, results of operations, contractual restrictions, capital requirements, business prospects and other factors that our Board of Directors considers relevant. Our Board of Directors has authorized the repurchase of shares of our common stock, par value $.01 per share. The Board of Directors authorized the expenditure of up to $50 million to repurchase shares over a two-year period ending February 16, 2007.

Selected Financial Data

      You should read the following discussion and analysis together with our consolidated financial statements and the notes to those statements included elsewhere in this Annual Report on Form 10-K.

Overview

      We provide a broad range of products and services to the oil and gas industry through our offshore products, tubular services and well site services business segments. Demand for our products and services is cyclical and substantially dependent upon activity levels in the oil and gas industry, particularly our customers’ willingness to spend capital on the exploration for and development of oil and gas reserves. Demand for our products and services by our customers is highly sensitive to current and expected oil and natural gas prices. Generally, our tubular services and well site services segments respond more rapidly to shorter-term movements in oil and natural gas prices than our offshore products segment. Our offshore products segment provides highly engineered and technically designed products for offshore oil and gas development and production systems and facilities. Sales of our offshore products and services depend upon the development of offshore production systems, repairs and upgrades of existing drilling rigs and construction of new drilling rigs. In this segment, we are particularly influenced by deepwater drilling and production activities, which are driven largely by our customers’ outlook for longer-term future oil prices. Through our tubular services segment, we distribute a broad range of casing and tubing. Sales of tubular products and services depend upon the overall level of drilling activity, the types of wells being drilled and the level of oil country tubular goods (OCTG) pricing. Historically, tubular services gross margins expand during periods of rising OCTG prices and contract during periods of decreasing OCTG prices. In our well site services business segment, we provide shallow land drilling services, hydraulic well control services, work force accommodations, catering and logistics services and rental tools. Demand for our drilling services is driven by land drilling activity in Texas, New Mexico, Ohio and in the Rocky Mountains area in the U.S. Our workover services are conducted in the U.S., South America, Africa, and the Middle East and are dependent upon the level of workover activity in those areas. Our rental tools and services depend primarily upon the level and type of drilling, completion and workover activity in the U.S., Canada and Central and South America. Our accommodations business is conducted primarily in Canada and its activity levels have historically been driven by oil and gas drilling and mining activities. In the past year, we have seen increased demand in our work force accommodation business as a result of oil sands development activities in Northern Alberta, Canada. Our revenues derived from oil sands development activities in our accommodations business have increased from $46.8 million, or 24.6% of total accommodations revenues in 2004, to $131.0 million, or 45.6% of total accommodations revenues in 2005. We are continuing to see significant opportunities to make capital investments as a result of oil sands development activities in Alberta, Canada. We support remote accommodations needs primarily in the U.S. and Canada.

      We have a diversified product and service offering which has exposure throughout the oil and gas cycle. Demand for our tubular services and well site services segments are highly correlated to changes in the rig count in the United States and Canada. The table below sets forth a summary of North American rig activity, as measured by Baker Hughes Incorporated, as of and for the periods indicated.

      The average North American rig count for the year ended December 31, 2005 increased by 282 rigs, or 18.1%, compared to the year ended December 31, 2004. This overall increase in activity, while tempered somewhat by lower activity levels in the U.S. Gulf of Mexico, did contribute to increased revenues in our tubular services and well site services segments. Our well site services segment results for the year 2005 also benefited from capital spending, which aggregated $73.0 million in the year ended December 31, 2005, the acquisition of Elenburg on February 1, 2005 for total consideration of $22.1 million, the acquisition of Stinger

on May 1, 2005 and June 1, 2005 for total consideration of $96.1 million and the impact of increased activity levels and pricing gains in certain business lines. The Canadian rig count increased 24.1% in the year 2005 compared to the year 2004. Our remote accommodations, catering and logistics services activities benefited from increased activities in the Northern Alberta oil sands area and, to a lesser extent, from the Canadian rig count increase.

      Hurricanes Katrina and Rita did not materially affect our operating results in 2005 despite some activity delays and lack of cost absorption in some of our manufacturing facilities. Our activities which were negatively impacted by the storms were offshore tubular (OCTG) sales, offshore rental tools usage and some temporary downtime in our offshore products manufacturing facilities in Houma, Louisiana and Houston, Texas. Repair activity resulting from these hurricanes has benefited our offshore products and U.S. Gulf accommodations businesses. Prolonged periods of reduced offshore activity due to repair efforts could negatively impact offshore drilling and workover activity which would adversely affect our hydraulic workover and rental tool businesses in addition to delaying OCTG sales.

      During 2005, the results generated by our Canadian workforce accommodations, catering and logistics operations benefited from the strengthening of the Canadian currency, which we generally do not hedge. For the year ended December 31, 2005, the Canadian dollar averaged $0.83 U.S. dollars to each Canadian dollar compared to $0.77 for the year ended December 31, 2004, an increase of 7.8%.

      On May 11, 2004, our tubular services segment purchased the OCTG distribution business of Hunting Energy Services, L.P. (Hunting) for $47.2 million, including purchase price adjustments. On June 2, 2005 we acquired all of the outstanding stock of Phillips for total consideration of $31.2 million. Both of these acquisitions resulted in increased OCTG inventory and revenues from the date of acquisition. Our tubular services segment shipped 405,300 tons of OCTG in 2005 (118,600 tons in the fourth quarter of 2005) compared to 339,800 tons in 2004 (97,800 tons in the fourth quarter of 2004). Our tubular services segment benefited in the past year from an 18.4% year over year increase in average U.S. land drilling activity, the acquisition of the Hunting and Phillips OCTG distribution businesses and increased OCTG prices. Our tubular services gross margins were at historically high levels in 2004 and 2005. The tubular services gross margin as a percent of revenues increased to 12.2% in 2005 compared to a gross margin percent of 11.9% in 2004. In 2002 and 2003, gross margins were 6.4% and 5.8%, respectively. Increases and decreases in gross margins are attributable to many factors including fundamental supply and demand, timing and frequency of price changes for inventory sold and the mix of OCTG grades sold. Typically alloy OCTG grades carry a higher margin than carbon OCTG grades. We increased slightly the percentage of carbon grade OCTG in our inventory with the acquisition of Phillips.

      Our offshore products segment reported much improved operating results in 2005 compared to 2004 as a result of increased activity and greater fixed cost absorption. Our offshore products backlog totaled $110.7 million at December 31, 2005 and $97.5 million at December 31, 2004. We believe that the offshore construction and development business is characterized by lengthy projects and a long “lead-time” order cycle. While change in backlog levels from one quarter to the next does not necessarily evidence a long-term trend, we believe activity levels in our offshore products segment will increase in future quarters, given the strength in our backlog at December 31, 2005 in addition to strong business prospects.

      Management believes that fundamental oil and gas supply and demand factors will continue to support a high level of drilling activity in North America which should continue to positively impact the Company, particularly its tubular services and well site service segments. However, recent declines in natural gas prices could lead to reduced drilling activity in the near term which would negatively impact our operating and financial results. Our customers are increasing their spending on deepwater offshore exploration and development which should benefit our offshore products segment. However, there can be no assurance that our expectations will be realized and there is a risk that high energy prices could negatively impact worldwide economic growth and, correspondingly, reduce the demand for energy causing oil and gas expenditures to decline which would be adverse to our business.

Consolidated Results of Operations

     Year Ended December 31, 2005 Compared to Year Ended December 31, 2004

      Revenues. Total revenues increased $560.6 million, or 57.7%, to $1,531.6 million during the year ended December 31, 2005 compared to revenues of $971.0 million during the year ended December 31, 2004. Offshore products revenues increased $64.4 million, or 31.1%, due to higher activity levels supporting offshore production facility construction. Tubular services revenues and tons shipped increased $284.4 million, or 66.6%, and 65,500 tons, or 19.3%, respectively, in the year ended December 31, 2005 compared to the year ended December 31, 2004 due to increased industry demand, higher OCTG prices, the Hunting acquisition completed in May 2004 and the Phillips acquisition that closed in June 2005. Our average OCTG selling prices increased 39.8% from the year 2004 to the year 2005. Well Site services revenues increased $211.8 million, or 62.9%, to $548.7 million for the year 2005 compared to $336.9 million for the year 2004. Our drilling revenues increased $40.3 million, or 86.9%, because of contributions from the Elenburg acquisition, which added seven rigs in February 2005, higher dayrates earned and additional rigs added to the fleet. The Elenburg acquisition contributed $21.8 million of the $40.3 million increase in revenues generated from the Company’s drilling operations. Our hydraulic workover revenues increased by $6.3 million, or 18.8%, in the year 2005 compared to the year 2004 because of higher activity in our primary operating areas, especially the U.S. Gulf of Mexico and Venezuela. Rental tools generated revenues in the year ended December 31, 2005 of $134.8 million, which were $67.9 million, or 101.5%, higher than the year ended December 31, 2004 due to the acquisition of Stinger, capital expenditures made since last year, improving U.S. drilling activity and modest price increases. The Stinger acquisition accounted for $55.3 million of the $67.9 million revenue increase generated by the Company’s rental tools business line. Accommodations revenues in the year ended December 31, 2005 were $287.3 million, an increase of $97.3 million, or 51.2%, over the accommodations revenues reported in the year ended December 31, 2004 primarily because of increased activity in support of the oil sands developments in Canada.

      Gross Margin. Our gross margins, which we calculate before a deduction for depreciation expense, increased $129.1 million, or 65.7%, from $196.4 million in the year ended December 31, 2004 to $325.5 million in the year ended December 31, 2005. Our overall gross margin as a percent of revenues was 21.3% in the year 2005 compared to 20.2% in 2004. Gross margin percentages increased in all businesses except accommodations where a greater percentage of revenues was generated by manufacturing activities which generally earn a significantly lower margin than accommodations rental and service activities.

      Total gross margins at offshore products were $61.7 million in the year 2005 compared to $37.6 million in 2004, representing an increase of 64.1%. Offshore products gross margin percentage improved from 18.2% in 2004 to 22.8% in 2005 due to higher activity, which resulted in greater overhead absorption, and cost savings and efficiencies resulting from manufacturing facility consolidations that occurred in 2004.

      Tubular services gross margins increased $35.8 million, or 70.6%, in the year ended December 31, 2005 compared to the year ended December 31, 2004 as a result of price increases and increased oil and gas drilling activity which strengthened demand for our tubular products and services. Our tubular services segment gross margin as a percent of revenues increased from 11.9% in 2004 to 12.2% in 2005.

      Well Site services gross margins increased by $69.2 million, or 64.0%, in the year 2005 compared to the year 2004. Well Site services gross margin as a percentage of revenues increased slightly to 32.3% in 2005 compared to 32.1% in 2004. Drilling gross margins in the year ended December 31, 2005 totaled $32.9 million compared to $14.6 million in the year ended December 31, 2004, an increase of $18.3 million, or 125.3%. Of the $18.3 million increase in drilling gross margins, $8.7 million was generated by the Elenburg acquisition and one of our newly constructed rigs placed in service in June 2005 in the Rocky Mountain area. Our drilling services gross margin percentage improved to 37.9% of revenues in 2005 from 31.5% of revenues in 2004 due to higher dayrates and a move from billing on a footage rate basis to billing on a dayrate basis for many of our drilling rigs. Under a daywork drilling contract, the customer pays for certain costs that the Company would normally provide when drilling on a footage basis and assumes more risks than on a footage basis. Workover gross margins improved by $4.2 million, or 55.3%, in the year 2005 compared to the prior year because of higher activity in the U.S. Gulf of Mexico and Venezuela. The workover gross margin percentage increased to 29.6% of revenues for 2005 compared to 22.6% in the year 2004 due primarily to higher utilization and

dayrates. Rental tools gross margins totaled $66.4 million in the year ended December 31, 2005 compared to $30.4 million in the year ended December 31, 2004, an increase of $36.0 million, or 118.4%. Rental tools gross margin percentage increased from 45.4% for the year 2004 to 49.3% in 2005. The improvement resulted from higher utilization of tools, modestly higher rental rates and the positive impact of the Stinger acquisition. Accommodations gross margins in the year ended December 31, 2005 totaled $66.2 million compared to $55.5 million in the year ended December 31, 2004, an increase of $10.7 million, or 19.3%. The gross margin percentage declined to 23.0% during 2005 compared to the 29.2% gross margin percentage realized during 2004 due to a higher relative mix of lower margin manufacturing revenues, extended warm weather during the fourth quarter and increased mobilization costs in late 2005 compared to late 2004.

      Selling, General and Administrative Expenses. Selling, general and administrative expenses (SG&A) increased $19.9 million, or 30.6%, for the year 2005 compared to 2004. During the year ended December 31, 2005, SG&A totaled $84.7 million, or 5.5% of revenues, compared to SG&A of $64.8 million, or 6.7% of revenues, for the year ended December 31, 2004. SG&A did not increase at the same rate as revenues as we were able to successfully leverage our fixed cost structure. Increased SG&A expense associated with acquisitions completed since 2004, higher ad valorem taxes for increased levels of OCTG inventory, increased incentive compensation expense, and higher professional fees associated with Sarbanes-Oxley compliance were the primary factors causing increased SG&A in 2005 compared to 2004.

      Depreciation and Amortization. Depreciation and amortization expense increased $10.7 million, or 29.8%, in the year 2005 compared to the year 2004 due primarily to acquisitions of businesses and capital expenditures made in the past year.

      Operating Income. Our operating income represents revenues less (i) cost of sales, (ii) selling, general and administrative expenses, (iii) depreciation and amortization expense, and (iv) other operating (income) expense. Our operating income increased $99.5 million, or 104.6%, to $194.6 million for the year ended December 31, 2005 from $95.1 million for the year ended December 31, 2004. Offshore products operating income increased $19.4 million, tubular services operating income increased $34.0 million and well site services operating income increased $49.2 million. These increases were partially offset by higher corporate costs of $3.1 million.

      Interest Expense. Interest expense increased $6.2 million, or 81.3%, for the year ended December 31, 2005 compared to the year ended December 31, 2004. Interest expense increased due to higher debt levels resulting from acquisitions completed since December 31, 2004 and capital expenditures, combined with higher interest rates.

      Income Tax Expense. Income tax expense totaled $60.7 million, or 33.3% of pretax income, during the year ended December 31, 2005 compared to $29.4 million, or 33.1% of pretax income, during the year ended December 31, 2004. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Tax Matters” discussion below.

      Revenues. Revenues increased $247.3 million, or 34.2%, to $971.0 million during the year ended December 31, 2004 compared to revenues of $723.7 million during the year ended December 31, 2003. Tubular services revenues and tons shipped increased $191.6 million, or 81.3%, and 70.8 thousand tons, or 26.3%, respectively, in the year ended December 31, 2004 compared to revenues and tons shipped in the year ended December 31, 2003 due to increased industry demand, higher OCTG prices, and contributions from the acquisition of the Hunting OCTG distribution business which was closed in May 2004. Well site services revenues increased $80.8 million, or 31.6%, while offshore products revenues decreased $25.1 million, or 10.8%, during the same period. Well site services revenues increased compared to the prior year due primarily to increased drilling activity in the United States, increased oil sands development activity in Canada, an international catering and facilities management contract, favorable Canadian dollar exchange rates, the impact of capital expenditures made since December 31, 2003 and rental tool acquisitions which were acquired for total consideration of $52.0 million. These rental tool acquisitions were completed in the fourth quarter of 2003 and in January and April of 2004. Offshore products revenues decreased as a result of lower

activity supporting offshore production facility construction given the typical lengthy time period between offshore discoveries and installation of production facilities.

      Gross Margin. Our gross margins, which we calculate before a deduction for depreciation expense, increased $45.8 million, or 30.4%, from $150.6 million in the year ended December 31, 2003 to $196.4 million in the year ended December 31, 2004. Our overall gross margin as a percent of revenues was essentially flat in 2004 compared to 2003. Well site services gross margins increased $27.2 million, or 33.6%, to $108.1 million in the year ended December 31, 2004 compared to the year ended December 31, 2003. Within our well site services segment, our shallow drilling and specialty rental tool businesses’ gross margins increased $4.3 million, or 41.7%, and $9.0 million, or 42.1%, respectively, during the year ended December 31, 2004 compared to the year 2003. Three drilling rigs were added in our shallow drilling business (added in December 2003, February 2004 and December 2004). In addition, we realized higher utilization and footage drilling rates for all of our drilling rigs and contributions from rental tool acquisitions completed in the fourth quarter of 2003 and in January and April 2004. Also in well site services, our work force accommodations, catering and logistics services and modular building construction services gross margins increased by $14.8 million, or 36.4%, in the year ended December 31, 2004 compared to the year ended December 31, 2003 primarily because of increased camp and catering activity supporting oil sands development in Canada and an international catering and facilities management contract. Our hydraulic workover gross margins decreased by $0.9 million, or 10.6%, as a result of decreased utilization, especially in West Africa and the Middle East. Our well site services gross margin percent increased slightly to 32.1% in the year ended December 31, 2004 compared to 31.6% in the year ended December 31, 2003.

      Offshore products gross margins decreased $18.4 million, or 32.9%, from $56.0 million in the year ended December 31, 2003 to $37.6 million in the year ended December 31, 2004 due to decreased activity, reduced fixed cost absorption and inefficiencies associated with various facilities consolidations undertaken during 2004. Additionally, offshore products margins were lower in 2004 compared to 2003 due to a less favorable mix of higher margin connector products. These factors caused offshore products gross margin percent to decline from 24.1% of revenues in the year 2003 to 18.2% in the year 2004.

      Tubular services gross margins increased to $50.7 million, or 11.9% of tubular services revenues, in the year ended December 31, 2004 compared to $13.7 million, or 5.8% of tubular services revenues, in the year ended December 31, 2003 as a result of increased oil and gas drilling activity which increased demand for our tubular products and services, a significant increase in OCTG prices during 2004 and the acquisition of the OCTG distribution business of Hunting for $47.2 million in May 2004, including a purchase price adjustment settled in October 2004. Tubular services margins expanded during 2004 and reached historically high levels given the significant increase in OCTG prices coupled with strong demand.

      Selling, General and Administrative Expenses. During the year ended December 31, 2004, selling, general and administrative expenses (SG&A) totaled $64.8 million, or 6.7% of revenues, compared to SG&A of $57.7 million, or 8.0% of revenues, for the year ended December 31, 2003. SG&A expense increased primarily as a result of acquisitions completed in 2003 and 2004, higher postretirement benefit costs in 2004 due to the recording of a gain upon settlement of plan liabilities in 2003, higher professional fees and higher bonus accruals under the incentive compensation plan. The increase in professional fees was largely attributable to costs associated with Sarbanes-Oxley compliance.

      Depreciation and Amortization. Depreciation and amortization expense increased $8.1 million in 2004 compared to 2003 due primarily to acquisitions of businesses completed since 2003 and capital expenditures made in 2003.

      Operating Income. Our operating income represents revenues less (i) cost of sales, (ii) selling, general and administrative expenses, (iii) depreciation and amortization expense, and (iv) other operating expense (income). Our operating income increased $29.9 million, or 45.9%, to $95.1 million for the year ended December 31, 2004 from $65.2 million for the year ended December 31, 2003. Well site services operating income increased $18.3 million from 2003 to 2004. Offshore products operating income decreased $20.7 million while tubular services operating income increased $34.9 million. Corporate and other charges increased by $2.6 million in 2004 compared to 2003.

      Interest Expense. Interest expense was lower by $0.2 million in the year ended December 31, 2004 compared to the year ended December 31, 2003. Increased interest expense attributable to higher debt levels resulting from acquisitions completed during the first half of 2004 and higher interest rates in 2004 was more than offset by lower debt issuance cost amortization compared to 2003.

      Income Tax Expense. Income tax expense totaled $29.4 million, or 33.1% of pretax income, during the year ended December 31, 2004 compared to $14.2 million, or 24.2% of pretax income, during the year ended December 31, 2003. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Tax Matters” discussion below.

      Our primary liquidity needs are to fund capital expenditures, such as expanding our accommodations facilities, expanding and upgrading our manufacturing facilities and equipment, increasing and replacing our drilling rig, rental tool and workover assets, funding new product development and funding general working capital needs. In addition, capital is needed to fund strategic business acquisitions. Our primary sources of funds have been cash flow from operations, proceeds from borrowings under our bank facilities and, more recently, proceeds from our convertible note offering (see Note 7 to Consolidated Financial Statements included in this Annual Report on Form 10-K).

      Cash totaling $33.4 million was provided by operations during the year ended December 31, 2005 compared to cash totaling $97.2 million provided by operations in the year ended December 31, 2004. During 2005, $138.2 million was used to fund working capital. Significantly increased working capital was invested in tubular services inventory ($129.1 million of total working capital invested for 2005) due to increased volumes and prices paid. At December 31, 2005, our tubular services inventory increased 70,000 tons from December 31, 2004 and the per ton cost of inventory also increased from $1,192 per ton at December 31, 2004 to $1,578 per ton at December 31, 2005. Additionally, trade receivables increased as a result of higher revenues and were only partially offset by higher accounts payable and accrued liability levels.

      Cash was used in investing activities during the years ended December 31, 2005 and 2004 in the amount of $229.9 million and $137.7 million, respectively. Capital expenditures totaled $83.4 million and $60.0 million during the years ended December 31, 2005 and 2004, respectively. Capital expenditures in both years consisted principally of purchases of assets for our well site services segment. In addition, we completed various acquisitions totaling $147.6 million and $80.8 million net of cash acquired, during the years 2005 and 2004, respectively.

      On February 1, 2005, we completed the acquisition of Elenburg Exploration Company, Inc. (Elenburg), a Wyoming based land drilling company for cash consideration of $21.3 million, net of cash acquired and including transaction costs, but excluding a note payable to the former owners of $0.8 million. Elenburg owned and operated 7 rigs which provide shallow land drilling services in Montana, Wyoming, Colorado, and Utah.

      Effective May 1, 2005 we acquired Stinger Wellhead Protection, Inc., certain affiliated companies and related intellectual property and, effective June 1, 2005, we completed the acquisition of Stinger’s international operations (collectively, Stinger) for cash consideration of $84.7 million, net of cash acquired and including transaction costs, but excluding a note payable to the former owners of $5.0 million. Stinger provides wellhead isolation equipment and services through its 29 locations in the United States, Canada, Central and South America. Stinger’s patented equipment is utilized during pressure pumping operations and isolates the customers’ blow-out preventers or wellheads from the pressure and abrasion experienced during the fracturing process of an oil or gas well. The Stinger acquisition expanded our rental tool and services capabilities, especially in the pressure pumping market.

      On June 2, 2005, we purchased Phillips Casing and Tubing, L.P. (Phillips) for cash consideration of $31.2 million, including transaction costs. Phillips distributes oil country tubular goods (OCTG), primarily carbon ERW (electronic resistance welded) pipe, from its facilities in Midland and Godley, Texas.

      On June 6, 2005, we acquired Noble Structures, Inc. for cash consideration of $7.9 million, including transaction costs, but excluding a note payable of $0.8 million. The acquisition expanded our accommodation

manufacturing capabilities in Canada in order to meet increased demand for remote site facilities, principally in the oil sands region.

      The cash consideration paid for all of our acquisitions in the period was initially funded utilizing our existing bank credit facility and a $25 million bridge loan (See Note 7 to the Consolidated Financial Statements included in this annual report on Form 10-K). Accounting for the acquisitions made in the period has not been finalized and is subject to adjustments during the purchase price allocation period, which is not expected to exceed a period of one year from the respective acquisition dates.

      We currently expect to spend a total of approximately $125.0 million for capital expenditures during 2006, for maintenance and upgrade of our equipment and facilities and also to expand our product and service offerings. We expect to fund these capital expenditures with internally generated funds and proceeds from borrowings under our revolving credit facilities.

      Net cash of $195.3 million was provided by financing activities during the year ended December 31, 2005, primarily as a result of revolving credit borrowings and the issuance of $175 million aggregate principal amount of 2 3/8% contingent convertible senior notes due in 2025 (2³/8% notes) in the second and third quarters of 2005. See Note 7 to the Consolidated Financial Statements included in this Annual Report on Form 10-K. Net proceeds from the 2³/8% notes were utilized to repurchase $30 million of our common stock, which was classified as treasury stock at December 31, 2005, to repay an outstanding bridge loan of $25 million and to repay indebtedness of $114.5 million under our revolving credit facility. During the first quarter of 2005, our Board of Directors authorized the repurchase of up to $50 million of our common stock, par value $.01 per share, over a two year period. Through December 31, 2005, a total of $30 million of our stock (1,183,432 shares), acquired with a portion of the proceeds from the issuance of the 2³/8% notes, has been repurchased under this program. No shares of our stock were repurchased during the three months ended December 31, 2005 and a total of up to $20 million remains available under the program.

      Our primary bank credit facility (the Credit Facility), which matures in January 2010, provides for $325 million of revolving credit. The credit agreement, which governs our Credit Facility (the Credit Agreement), contains customary financial covenants and restrictions, including restrictions on our ability to declare and pay dividends. Borrowings under the Credit Agreement are secured by a pledge of substantially all of our assets and the assets of our subsidiaries. Our obligations under the Credit Agreement are guaranteed by our significant subsidiaries. Borrowings under the Credit Agreement accrue interest at a rate equal to either LIBOR or another benchmark interest rate (at our election) plus an applicable margin based on our leverage ratio (as defined in the Credit Agreement). We must pay a quarterly commitment fee, based on our leverage ratio, on the unused commitments under the Credit Agreement. During the year 2005, our applicable margin over LIBOR ranged from 1% to 2% and it was 1.25% as of December 31, 2005. Our weighted average interest rate paid under the Credit Agreement was 4.6% during the year ended December 31, 2005 and 3.6% for the year ended December 31, 2004.

      As of December 31, 2005, we had $222.5 million outstanding under the Credit Facility and an additional $12.0 million of outstanding letters of credit, leaving $90.5 million available to be drawn under the facility. In addition, we have other floating rate bank credit facilities in the U.S. and the U.K. that provide for an aggregate borrowing capacity of $8.4 million. We had no borrowings outstanding under these other facilities as of December 31, 2005. Our total debt represented 39.0% of our total capitalization at December 31, 2005.

      We believe that cash from operations and available borrowings under our credit facilities will be sufficient to meet our liquidity needs in the coming twelve months. If our plans or assumptions change or are inaccurate, or if we make further acquisitions, we may need to raise additional capital. However, there is no assurance that we will be able to raise additional funds or be able to raise such funds on favorable terms.

      The following summarizes our debt and lease obligations at December 31, 2005 (in thousands):

      Our debt obligations at December 31, 2005 are included in our consolidated balance sheet, which is a part of our consolidated financial statements included in this Annual Report on Form 10-K. We have not entered into any material leases subsequent to December 31, 2005. We do not have any off balance sheet arrangements.

      Our primary deferred tax asset, which totaled $9.8 million at December 31, 2005, is related to $27.9 million in available federal net operating loss carryforwards, or NOLs, as of that date. The NOLs will expire in varying amounts during the years 2010 through 2011 if they are not first used to offset taxable income that we generated. Our ability to utilize a significant portion of the NOLs is currently limited under Section 382 of the Internal Revenue Code due to a change of control that occurred during 1995. We currently believe that substantially all of our NOL’s will be utilized.

      Our income tax provision for the year ended December 31, 2005 totaled $60.7 million or 33.3% of pretax income. The income tax provision for the year 2005 included a $4.7 million income tax benefit related to the reversal of substantially all of the remaining valuation allowance applied against NOLs which were recorded as of the prior year end. Based upon a review of the potential effects of all pertinent evidence, we have concluded that substantially all of the remaining valuation allowance which we had recorded against our NOL deferred tax asset was unnecessary.

Critical Accounting Policies

      In our selection of critical accounting policies, our objective is to properly reflect our financial position and results of operations in each reporting period in a manner that will be understood by those who utilize our financial statements. Often we must use our judgment about uncertainties.

      There are several critical accounting policies that we have put into practice that have an important effect on our reported financial results.

      We have contingent liabilities and future claims for which we have made estimates of the amount of the eventual cost to liquidate these liabilities or claims. These liabilities and claims sometimes involve threatened or actual litigation where damages have been quantified and we have made an assessment of our exposure and recorded a provision in our accounts to cover an expected loss. Other claims or liabilities have been estimated based on our experience in these matters and, when appropriate, the advice of outside counsel or other outside experts. Upon the ultimate resolution of these uncertainties, our future reported financial results will be impacted by the difference between our estimates and the actual amounts paid to settle a liability. Examples of areas where we have made important estimates of future liabilities include litigation, taxes, fines, penalties, interest, warranty claims, contract claims and discontinued operations.

      The determination of impairment on long-lived assets, including goodwill, is conducted when indicators of impairment are present. If such indicators were present, the determination of the amount of impairment would be based on our judgments as to the future operating cash flows to be generated from these assets throughout their estimated useful lives. Our industry is highly cyclical and our estimates of the period over which future cash flows will be generated, as well as the predictability of these cash flows, can have a significant impact on the carrying value of these assets and, in periods of prolonged down cycles, may result in impairment charges.

      We recognize revenue and profit as work progresses on long-term, fixed price contracts using the percentage-of-completion method, which relies on estimates of total expected contract revenue and costs. We follow this method since reasonably dependable estimates of the revenue and costs applicable to various stages of a contract can be made. Recognized revenues and profit are subject to revisions as the contract progresses to completion. Revisions in profit estimates are charged to income or expense in the period in which the facts and circumstances that give rise to the revision become known. Provisions for estimated losses on uncompleted contracts are made in the period in which losses are determined.

      Our valuation allowances, especially related to potential bad debts in accounts receivable and to obsolescence or market value declines of inventory, involve reviews of underlying details of these assets, known trends in the marketplace and the application of historical factors that provide us with a basis for recording these allowances. If market conditions are less favorable than those projected by management, or if our historical experience is materially different from future experience, additional allowances may be required. We have, in past years, recorded a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. See “Note 9 — Income Taxes” and “Tax Matters” herein.

      The selection of the useful lives of many of our assets requires the judgments of our operating personnel as to the length of these useful lives. Should our estimates be too long or short, we might eventually report a disproportionate number of losses or gains upon disposition or retirement of our long-lived assets. We believe our estimates of useful lives are appropriate.

      In purchase transactions, we must estimate the fair values of assets and liabilities acquired. Judgment is required to determine these valuations and amounts assigned to individual assets and liabilities will impact future results of operations.

      In November 2004, the FASB issued Statement of Financial Accounting Standards No. 151, “Inventory Costs — an amendment of ARB 43, Chapter 4” (“SFAS 151”). SFAS 151 clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs and wasted material. Paragraph 5 of Accounting Research Bulletin (“ARB”) 43, Chapter 4 “Inventory Pricing,” previously stated that “. . .under certain circumstances, items such as idle facility expense, excessive spoilage, double freight, and rehandling costs may be so abnormal as to require treatment as current-period charges. . .” SFAS 151 requires that those items be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal.” In addition, SFAS 151 requires that the allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS 151 is effective for fiscal years beginning after June 15, 2005. The Company does not believe the implementation of SFAS 151 will have a material impact on the Company’s financial position, results of operations or cash flows.

      On December 16, 2004, the FASB issued FASB Statement No. 123 (revised 2004), Share-Based Payment, which is a revision of FASB Statement No. 123, Accounting for Stock-Based Compensation. Statement 123(R) supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees, and amends FASB Statement No. 95, Statement of Cash Flows. Generally, the approach in Statement 123(R) is similar to the approach described in Statement 123. However, Statement 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Pro forma disclosure is no longer an acceptable alternative.

      As permitted by SFAS No. 123, the Company currently accounts for share-based payments to employees using the APB No. 25 intrinsic value method and, as such, generally recognizes no compensation cost for employee stock options. Accordingly, the adoption of SFAS No. 123(R)’s fair value method will have an impact on our results of operations, although it will have no impact on our overall financial position. Had we adopted SFAS No. 123(R) in prior periods, the impact of that standard would have approximated the impact of SFAS No. 123 as described in the disclosure of pro forma net income and earnings per share in Note 12 of this Annual Report on Form 10-K. Statement No. 123(R) also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash flow, rather than as an operating cash flow. This requirement will reduce net operating cash flows and increase net financing cash flows in

periods after adoption. While the company cannot estimate what those amounts will be in the future (because they depend on, among other things, when employees exercise stock options), the amount of operating cash flows recognized in prior periods for such excess tax deductions for stock option exercises were $3.7 million, $1.1 million and $1.8 million in 2005, 2004 and 2003, respectively. We adopted the provisions of this Statement on January 1, 2006, using the modified prospective method, and continue to study the provisions of this new pronouncement to determine the impact on our financial statements.

      In May 2005, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 154, “Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3.” Among other changes, this Statement requires retrospective application for voluntary changes in accounting principles, unless it is impractical to do so. Guidance is provided on how to account for changes when retrospective application is impractical. This Statement is effective on a prospective basis beginning January 1, 2006.

      Interest Rate Risk. We have long-term debt and revolving lines of credit subject to the risk of loss associated with movements in interest rates. As of December 31, 2005, we had floating rate obligations totaling approximately $222.5 million for amounts borrowed under our revolving credit facilities. These floating-rate obligations expose us to the risk of increased interest expense in the event of increases in short-term interest rates. If the floating interest rate were to increase by 1% from December 31, 2005 levels, our consolidated interest expense would increase by a total of approximately $2.2 million annually.

      Foreign Currency Exchange Rate Risk. Our operations are conducted in various countries around the world in a number of different currencies. As such, our earnings are subject to movements in foreign currency exchange rates when transactions are denominated in currencies other than the U.S. dollar, which is our functional currency, or the functional currency of our subsidiaries, which is not necessarily the U.S. dollar. In order to mitigate the effects of exchange rate risks, we generally pay a portion of our expenses in local currencies and a substantial portion of our contracts provide for collections from customers in U.S. dollars. During 2005, our realized foreign exchange gains were $0.2 million. These gains are included in other operating expense (income) in the consolidated statements of income.

      Our consolidated financial statements and supplementary data of the Company appear on pages 42 through 71 of this Annual Report on Form 10-K and are incorporated by reference into this Item 8. Selected quarterly financial data is set forth in Note 14 to our Consolidated Financial Statements, which is incorporated herein by reference.

      There were no changes in or disagreements on any matters of accounting principles or financial statement disclosure between us and our independent auditors during our two most recent fiscal years or any subsequent interim period.

      Our Chief Executive Officer and Chief Financial Officer performed an evaluation of our disclosure controls and procedures, which have been designed to permit us to effectively identify and timely disclose important information. They concluded that the controls and procedures were effective as of December 31, 2005 to ensure that material information was accumulated and communicated to the Company’s management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

      Pursuant to section 906 of The Sarbanes-Oxley Act of 2002, our Chief Executive Officer and Chief Financial Officer have provided certain certifications to the Securities and Exchange Commission. These certifications accompanied this report when filed with the Commission, but are not set forth herein.

MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL

OVER FINANCIAL REPORTING

To the Stockholders and Board of Directors of Oil States International, Inc.:

      The management of Oil States International, Inc. and subsidiaries (Oil States International, Inc. or the Company) is responsible for establishing and maintaining adequate internal control over financial reporting. Oil States International, Inc.’s internal control system was designed to provide reasonable assurance to the Company’s management and Board of Directors regarding the preparation and fair presentation of published financial statements.

      All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

      Oil States International, Inc.’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework. Based on our assessment we believe that, as of December 31, 2005, the Company’s internal control over financial reporting is effective based on those criteria.

      During 2005, the Company acquired Elenburg Exploration Company, Inc., Stinger Wellhead Protection, Inc. and related companies, and Noble Structures, Inc., in separate purchase business combinations. In reliance on guidance contained in a “Frequently Asked Questions” interpretive release issued by the staff of the SEC’s Office of Chief Accountant and Division of Corporation Finance in June 2004 (and revised on October 6, 2004), our management has elected to exclude Elenburg Exploration Company, Inc., Stinger Wellhead Protection, Inc. and related companies, and Noble Structures, Inc., from the scope of our assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005. These entities are wholly-owned subsidiaries of the Company at December 31, 2005. The total assets and total revenues of Elenburg Exploration Company, Inc., Stinger Wellhead Protection, Inc. and related companies, and Noble Structures, Inc., represent approximately 10.9% and 5.2%, respectively, of the total consolidated assets and total consolidated revenues of the Company as of and for the year ended December 31, 2005.

      Oil States International, Inc.’s independent registered public accounting firm has audited our assessment and the effectiveness of the Company’s internal control over financial reporting. This report appears on Page 47.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Oil States International, Inc.:

      We have audited the accompanying consolidated balance sheets of Oil States International, Inc. and subsidiaries (the “Company”) as of December 31, 2005 and 2004, and the related consolidated statements of income, stockholders’ equity and comprehensive income, and cash flows for each of the three years in the period ended December 31, 2005. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

      We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

      In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company at December 31, 2005 and 2004, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2005, in conformity with U.S. generally accepted accounting principles.

      We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company’s internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 1, 2006 expressed an unqualified opinion thereon.

OIL STATES INTERNATIONAL, INC. AND SUBSIDIARIES

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Oil States International, Inc.:

      We have audited management’s assessment, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting, that Oil States International, Inc. and subsidiaries (Oil States International, Inc. or the “Company”) maintained effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.

      We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

      A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

      Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

      As indicated in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Elenburg Exploration Company, Inc., Stinger Wellhead Protection, Inc. and related companies, and Noble Structures, Inc., which are included in the 2005 consolidated financial statements of Oil States International, Inc. and constituted approximately 10.9% and 5.2%, respectively, of total consolidated assets and total consolidated revenues of the Company as of and for the year ended December 31, 2005. Management elected not to assess the effectiveness of internal control over financial reporting at these entities because Oil States International, Inc. acquired these entities in purchase business combinations during 2005. Our audit of internal control over financial reporting of Oil States International, Inc. also did not include an evaluation of the internal control over financial reporting of Elenburg Exploration Company, Inc., Stinger Wellhead Protection, Inc. and related companies, and Noble Structures, Inc.

      In our opinion, management’s assessment that the Company maintained effective internal control over financial reporting as of December 31, 2005 is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005 based on the COSO criteria.

      We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the accompanying consolidated balance sheets of the Company as of December 31, 2005 and 2004 and the related consolidated statements of income, stockholders’ equity and other comprehensive income and cash flows for each of the three years in the period ended December 31, 2005 and our report dated March 1, 2006 expressed an unqualified opinion thereon.
